To ctZZ whom it may concern:

Be it known that I, RUSSEL Woos- WARD, a citizen. of the United States, residing at Wmikegsii, i'i'l the county of Lake, State of Illinois, have invented certain. new and useful. Improvements in Presser-Feet .lor Sewing-Machines, of which the following is s description, reforehce beinghad to the sccompsnying drawings and to the letters of refereticc method thereon.

My invention relates to an improvement in pressoisl eet for sewing-machines, and particulerly to a. pressewl'oot for use upozrmo- Chllla odsgited to sew lace edgings upon the necks or fronts of underwear, from the crossbars of which e 'sg s tape is drawn. sites na-tely over and under said hers. The presserdoot itsell may he said to he an intprovement upon the type of pro r-foot shown in the Pennington slid Soho potcnt,

ordinary straight/awsystitch and passes through the e L stod fshric upon, the opposite side of .it 'toon edging.

The integration intended connection with the sxtts n edging shown in. filed April 17, I the sewing on o t is ordinary giresserto be used in Tot for guiding my applies ion for patent lllo. 303,323. in 4 1; in the use cl tho oot it has hcen found that the feed is apt to pull one side of tho edging,

where the one side-es, tor instance, that to which the festoons applied siid which secured by the t o needles--is th' .1 than that pert which is operated upon by the other noodle. lithe hctom of the pressesfoot is in a. horizontal. plsi' that part of edging which is thickest will be fed; but hecsuse of this the feed sot not to take hold. of the this part of the goods, mod therefore the edging ed. the cogs; ovoid this difiic i ide con struotioli oi? pr 'srioot which can he edjiisted end rsil gpd to hear eqi'lsll' r on both .n to

ol. the pair or.

v Pem sides. of the edging and causes it to be fed equally.

The ii'wentioii consists 111 the matters herepcnded claims.

The invention is illustrated in the accompanying drawings, in whioh' Figure 1 represents a. front elevstior of a. portion of s sewingmiatchino, showing my improved resser-foot applied thereto. Fig. 2 is a plan. View (it the Presser-loot. F 1g. 3'

The presscr foot A formed with openings for the possage of the needles, and at its forward end is the spur-roller, similar to that shown in the gtoii end Scliott patent above reierre d to. 11 two downwardly-extending the slcml; F the resser-foot passes a. pin poo which the foot is pivoted to swing on i i parallel to the direction of feed.

By loosening one screw f and tightening the other t he Presser-foot may be tilted on its longitudinal axis, thus allowing for a. greater thickness of the edge on one side than on the flanges b F), through which and the lower end 1 other, so that the feed will. he equal on both I ters Patent, is

side the Work is not balanced. In other words, there is more resistance upon one side than upon the other, for the reason that on the twin-needle side there is a resistance from apair of tensions, while upon the other side there is the resistance of only one tension. Consequently it is necessary to have a construction of presser-foot to equalize it. This resistance is sometimes suflicient to draw thework out of line andpreventfeeding of the same without distorting the wales in the cloth, which is very objectionable. I consider this feature, therefore, within the scope of my invention and wish to cover it.

Having thus described my invention, what I claim as new, and desire to secure by Let- 1. A sewing-machine presser foot having needle-openings upon opposite sides of the central line, and pivoted to swin upon an axis parallel to the direction of reed, with whereby the difference in resistance of the fabric caused by the unequal pull of the i threads on opposite sides of the pivot is con1- I pensated for; substantially as described.

2. A sewing-machine presser-foot pivoted I to swing upon an axis parallel with the direction of feed of the machine, a yoke or plate secured to the shank of the presser-foot and bearing upon the presser-foot, with means for adjusting said presser-foot upon its axis; substantially as described.

3. A sewing-machine presser-foot pivoted to swing upon its axis parallel with the direction of feed of the machine, a yoke or plate secured to the shank of the pressersfoot and adjusting-screws passing through the opposite ends of the yoke, and bearing upon the presser-foot, whereby by loosening one and tightening the other, the foot may be tilted; substantially as described.

4. In combination with a sewing-machine, having a plurality of needles arranged unequally upon oppesite sides of the central line of feed, a resser-foot, pivoted to swim upon an axis parallel to the direction of fee with means for adjusting said foot on its axis whereby the fabric may be fed uniformly and without distortion; substantially as described.

In testimony whereof I afiix my signature presence of two witnesses.
